Abstract:

A three-dimensional unsteady flow was simulated using the Realiable k-ε turbulence model in full flow passage of a counter-rotating axial flow fan. Then, the frequency domain distributing of pressure pulsation was predicted at positions in two pairs of move-move interfaces and a pair of move-stator interfaces a  round the fore and after impellers. The spread and diversification rule of pressure pulsation along the radial direction of the interfaces was also analyzed. The simulation result indicated that the impact to the pressure pulsation a round impellers of the second impeller is much stronger than the first one. The results can be used as a reference of the numerical study on the aerodynamic noise field of axial flow fans.

Key words: counter-rotating axial flow fan; unsteady turbulent flow; pressure pulsation; realizable k-ε turbulence model
